I have tested the ModPCSkill fairly thoroughly and am not just posting hearsay. Let me explain the steps I have been through for anyone who is curious.
First I read about the problems. Then I looked at the problem in Oblivion using the tdt command on the console. I Scroll Locked around until I got to the Player Character Skill Usage page which shows
Skill (LEVEL): advances NUM: usage X.XX/X.XX
On initial Character creation, most skills look like this
Block (5): advances 0: usage 0.00/2.89
These numbers depend on which skill and what race you are. Then I invoked the console again and typed ModPCSkill Block 1 After which the line read Block (6): advances 1: usage -2.89/3.80 I repeated with Blade using the AdvancePCSkill and the result was the same.
Once given the chance I watched the Blade skill as I used my bladed weapon on an enemy. The usage value incremented as it should for each hit (it incremented by 0.5), but starting with the value of -2.89, not 0. So if it incremented by 0.5 it was going from -2.89/3.80 to -2.39/3.80. A new level is attained when it passes 3.80.
I have tested this with various mid-game saves on a single DELL Latitude D610 laptop with always the same result. This is a regularly reproducible bug which makes the ModPCSkill and AdvancePCSkill commands unusable in their current state.
